Don't forget the spin-offs from the NASA technologies.... There's an appreciable revenue hidden in there. Unless you are an US Citizen why complain how they spend their funds.
You seem to have got things mixed up. I never commented on Perseverance Rover's technology. Of course the Curiosity was designed more than a decade ago, the technologies here on Earth changed a lot and also NASA learned much from the near 10 year experience with the Curiosity Rover.yeah i know it works by seebeck effect and by design improvement i didn't mean that they move away from the first principal to nuclear fission or something in the 2nd one. you dont have a clear idea on what design improvement means. this is not the 2nd production unit of the same design. they should probably have changed and improved it learning on curiosity. same technology does not mean same design. even the body design is the same principal as curiosity. but they have done thousands of new simulations and design improvements to change tyre designs by learning on the mistakes on curiosity. by your logic, engines of ford model T and Toyota Premio is the same
I just commented on an observation by another member that the Perseverance even has an atomic power supply. Just wrote that it's not new but the same as that on Curiosity. You are talking about the tyres.... I am aware that they changed the width, diameter and the treads.
Just FYI, the power unit of the Rovers is not built by NASA at all. These has always been the DOE responsibility. Their scientists manufacture these units. As I said before, Radio Isotope Power unit technology itself is more than 50 years old, invented in the US. Even the Russian Lunokhod 1 & 2 and the Chinese lunar landers used this technology.
This is not to say that NASA was idling.... They have developed a unit named the Advanced Stirling Radioisotope Generator (ASRG) that can deliver four times the power than the current units per weight of the radio active material used. But it provides less heating that's needed in cold environments. Also there is the MHW (multi Hundred Watt RTG) under development. But these are not ready yet.
As you said I fully admit that I know nothing about design improvement... You are the expert. So could you please list the design improvements made on the Curiosity's MMRTG and the current Persevererance MMRTG.
yeah like those are in public domainYou seem to have got things mixed up. I never commented on Perseverance Rover's technology.

Yes... please do find it and let us know.... I wrote what I know and you said otherwise.yeah like those are in public domain
Sure you should know the differences.

Yeah true. But they got a very bad reputation regarding allocating budget. You know that they have spend few million dollars of money to invent a pen that will work on space while other countries like china,russia using pencils to write in space?Don't forget the spin-offs from the NASA technologies.... There's an appreciable revenue hidden in there. Unless you are an US Citizen why complain how they spend their funds.
But anyway new invations are more important imo. by the way your right we are not us citizens we have no right to say its good or bad bcz its not our tax money.Certainly their fund management had issues and questionable. But the story about the Pencil isn't quite true. In fact both the US and Soviet astronauts used pencils. NASA came under fire as they bought pencils at a cost of more than $100 per pencil.Yeah true. But they got a very bad reputation regarding allocating budget. You know that they have spend few million dollars of money to invent a pen that will work on space while other countries like china,russia using pencils to write in space?
NASA wasn't quite happy with Pencils as it created flakes, tips broke off and in microgravity this posed problems to equipment and pencils also are in the flammable items category. That's why they wanted a pen.
The Fisher Pen company apparently invested $1 Million for a space pen development project. So it wasn't NASA funds at all. Fisher patented & produced a pen that could write upside-down, in frigid or roasting conditions (down to minus 50 degrees Fahrenheit or up to 400 degrees F), and even underwater or in other liquids. If too hot, though, the ink turned green instead of its normal blue.
Afterwards they sold the Fisher AG-7 (Anti-Gravity) pen in bulk to NASA aroud $5 per piece. It was these that was used by NASA & the Soyuz missions. These had a pressurized Nitrogen cartridge (at 35 PSI) pushing the ink.
Much later on, they had another version called the "Shuttle Pen" used in the US Shuttles and in the Mir Space Station.
You can buy these on Amazon....
හොඳ වෙලාවට උඹ කිව්වේ මචන්. මේ දැන් NASA එක මට කතා කළා. උන් පිළිගත්ත අමු බොරුව කරන්නේ කියල. උඹට කුඹුරු වැඩ නවත්තල එන්න කිව්වා NASA එකේ rocket යවන්න.
NASA කියන්නේ ලොකු තැනක්. සැහෙන්න scientist ලා වැඩ කරනවා , නිකන් රුපියක් ලක්ස්හෙට දෙකට වැඩ කරන්නේ නැහැ උන් 
උන්ගේ research ම කොච්චර කරනවද.
අනික උන්ගේ annual budget එකම ඩොලර් මිලියන 24ක් වගේ. ඉතින් 2.5 මොකක්ද,
උන්ගේ research ම කොච්චර කරනවද.

For 2021 their budget is $25 Billion.NASA කියන්නේ ලොකු තැනක්. සැහෙන්න scientist ලා වැඩ කරනවා , නිකන් රුපියක් ලක්ස්හෙට දෙකට වැඩ කරන්නේ නැහැ උන්

Oh thanks for information many sites on the internet have mentioned the anti gravity pen project by nasa but dont know which is the truth good to know about this.
